extraParams for JSON store

Hi,

I'm happily using Ext Designer 1.2.2 build 48 for building up my GUI. At the moment I'm stuck with the neccessarity of using extraParams in a store definition: I need to pass the values of some other components which I need for the dynamic store logic. In a manually built app, I added the following definition to the store:

Since Ext Designer supports the extraParams definition as an "[object]" definition and I cannot check out how the formatting of this is: how to paste the above code snippet into the "extraParams" field for my store without messing the syntax? It seems that every singletick will be escaped by a backslash. Any hints are welcome.

is there already a workarround for this ? today i have tested the designer 2 and got the same problem,
only raw data is accepted ;-(( i would like to use functions wherevery the parameters accept objects or arrays.
any news about this ?
